"daddy"

So I was masturbating and my bf was telling me what to do to myself. This is nothing out of the ordinary but as I w as climaxing he whispered sooo sexily into my ear "cum for daddy" and it drove me wild! I've always been weirded out trying to call him 'daddy' during sex but OMG when he said it himself idk I feel like now if I try to call him that again it's guna sound sexy. Lol
